Hi,
Some time ago, someone asked a question about whether Zortech C++ 2.1
will run in the DOS extender mode under Windows 3.0 386 Enhanced mode.
(was it in comp.lang.c++ or comp.windows.ms ?)
Walter Bright replied with a resounding YES ! I tried on my machine
with the "-br" switch (if I remember correctly) on a small c++ program
and it works.
But I didn't see any typical DOS/Extender sign on message being
displayed (which other DOS extender programs tend to display). Which
lead me to suspect did the DOS extender C++ compiler actually run ?
Anybody with a big C++ code to try out ? I mean, if it really works,
then does this means program developed using Rational System's DOS
extender is DPMI compatible ?
Just curious.

yes to both questions. pleasantly enough (at least IMHO) ztc doesn't display
the dos extender sign on every time it is run. the dos extender version is
slightly (very slightly) slower than is the regular version but otherwise
works just the same.

All the -br flag does is run ZTCPP1R.EXE instead of ZTC1.EXE, the same
for the other passes. ZTCPP1R.EXE is a dos-extender program. The
banner that says it's a dos-extender program was removed.

Rational's latest version is DPMI compatible, if memory serves, versions
3.81 and later. That version is what ZTC was built with.
